Things are not all well in the production department of Marc Foster'sWorld War Z, the epic adaptation of Max Brooks' oral history of a fictitious global Zombie pandemic & near-apocalypse which stars Brad Pitt. Apparently Matthew Fox [Lost] & Ed Harris have both left the movie. Hit the jump for the details.

Matthew Fox and Ed Harris have bowed out of the film World War Z. Fox has left due to a scheduling conflict with Rob Cohen’s I, Alex Cross (Fox will be playing the film’s villain). It’s unknown why Harris opted out of WWZ, but now the production is scrambling to find two affordable but recognizable actors to fill the roles. Shooting is already underway and the producers are having actors read in both Los Angeles and London.

The project has already seen long delays, with Paramount Pictures eventually putting together a co-financing deal with Skydance Productions to cover the film's huge budget. Even still the project lingered which is quite strange considering there are few sub-genres more popular than Zombies these days. The story, adapted by J. Michael Straczynski, has Brooks [Pitt] as a journalist traveling around the world collecting stories of those that survived World War Z, a globe-spanning battle between humans and zombies that almost wiped out existence. The movie is currently in production in Malta, and new actors are being sought to fill these roles with all due haste in Los Angeles and London.
